all the cars at the track days i've attended (timed events, ie grip racing) are neatly prepared, seems just drift it's cool or acceptable to have shit hanging off the car everywhere
edit: about the cars that get drifted looking shit after a while, thats because a lot do half assed body mods when they install their sick widebody fibreglass kit and don't extend the wheel tub to the new guard with a piece of metal like you should to stop tyres ripping your guards off,.
